SummaryShould Yu International Trading (Shanghai) Co., Ltd. is a China-based trading company in Shanghai’s Pudong New District, with its business entity type also identified as Trading Company and Manufacturer/Factory. Its product scope includes food-grade and industrial salt, soda ash, sodium sulfate, magnesium sulfate, and calcium chloride. The supplied information describes access to substantial salt and chemical production capacity, including nine production lines and stated annual outputs for soda ash, sodium chloride, and refined salt. Quality-related evidence includes ISO 9001, ISO 14001, ISO 14064, HACCP, FSSC 22000, KOSHER, and HALAL references, although some certifications are presented in company descriptions rather than independently verified records. The supplier reports exports to multiple global regions and customer relationships involving recognized food and consumer brands, but evidence for after-sales service, customization, and detailed financial credibility is insufficient.

Supplier typeThe supplier is identified as a trade company in Shanghai, while its entity profile also states "Trading Company,Manufacturer/Factory." This indicates a trading-led business with manufacturer/factory capability or affiliation, but the slices do not clearly establish which products are manufactured directly by the legal entity.

CertificationsThe supplier information references ISO 9001, ISO 14001, ISO 14064, HACCP, FSSC 22000, KOSHER, and HALAL, and states that the production process conforms to several of these standards. This is explicit positive evidence of broad quality, food-safety, environmental, and religious-compliance certification coverage, although the slices do not provide certificate numbers, validity dates, or issuing-body verification.

R&D capabilityThe supplier reports 6–10 R&D engineers and describes the use of a Swiss SEP vacuum salt production process for PDV salt, with claimed high purity and uniform particle characteristics. This supports some process and product-development capability, but the slices do not provide evidence of patents, new product launches, dedicated R&D facilities, or measurable innovation outcomes.

Production capacityThe supplier describes 35 years of development, nine production lines, and stated annual outputs of 290,000 tons of soda ash, 300,000 tons of sodium chloride, and 300,000 tons of refined salt. It also reports a five-million-ton annual production capacity at the referenced ChinaSalt Kintan operation, supporting substantial production capability, although the slices do not fully clarify the exact ownership or allocation of all stated capacity to the Shanghai trading entity.

Client casesThe supplier states that ChinaSalt Jintan supplies or has served major companies including Nestle, Fonterra, Unilever, Pepsico, Mondelēz, KERRY, Heinz, and other domestic customers. Trade data also lists P D NAVKAR BIO CHEM PRIVATE LIMITED as an associated buyer, providing both claimed brand references and at least one recorded buyer association, although independent verification and transaction scope are not supplied.
